What is Rotator Cuff Injury?

Rotator Cuff muscles are a group of shoulder blade muscles that support the arm on the glenohumeral joint. As the shoulder is nested in a shallow socket and there is a lack of ligaments in this region, any weakness of the rotator cuff muscles makes it easy for partial dislocation, which is the head of the shoulder partially sliding way out of the socket, or full dislocation, when there is a complete slide out of the socket.

Injuries to rotator cuffs include: falling on an outstretched arm, lifting with faulty body mechanics and repetitive arm activities especially those done overhead like throwing a basketball or placing items on overhead shelves. Signs and symptoms of the injury include pain and tenderness in the shoulder area, weakness of shoulder muscles and limitation of shoulder motions.

What Is Frozen Shoulder?

Frozen shoulder, also known as adhesive capsulitis, is a condition where there is a restriction in the shoulder joints. Frozen shoulder creates intense contraction of the capsule that surrounds and supports the shoulder girdle. Muscles around the shoulder joints are inflamed and tender, restricting your movements and causing pain in the shoulder.

This condition typically happens to only one shoulder although one could have the condition on both shoulders. People with frozen shoulders will have difficulty with their normal daily activities such as combing their hair, putting on their shirts and scratching their backs.

What Causes Headache?

If you are experiencing a throbbing headache or find the lights too glaring, you are having a migraine. A migraine does not allow you to concentrate in your work and you may experience weakness, fatigue, or even feel nauseous. Symptoms may appear on one or both sides of your head or at the back of the eyes.

The human head weighs 4kg on average. If your head is not in correct alignment, for example, due to slouching or forwarded head posture, your cervical spine will have difficulties holding up the extra weight, due to the additional stress placed on the muscles and strain on your back and neck. In the long run, you may start getting neck pain, back pain and headaches or migraines.

What Causes Head Pain?

Long hours of hunching over the computer and poor working ergonomics will cause rounded shoulders and forwarded head posture, which gives rise to neck pain, shoulder pain, as well as head pain as they fall along the cervical spine. Long-term hunching of the back will also lead to shortness of breath and heart palpitations as it can congest your chest, lungs and thoracic area which is the rib cage and the upper spine area. Poor posture causes pain in these areas as well.

Often, one do not realize that bad posture is the cause of the pain and more often than not, they do not realize their postures have deviated from the proper posture, causing the pain to get much worse as the body is out of alignment. Some examples and causes of bad posture include walking with a slouch, carrying heavy weights on one side of your shoulders, reading while lying on your stomach and sitting in a curled-up position in front of the television.

Certain bad habits of daily activities can just be the cause, examples are:

• bad posture by slouching
• cradling the phone between the shoulder and neck for a prolonged period
• carrying a heavy load on one shoulder
• leaning on one leg while commuting in the bus or train
